It's important to grab receivers while they are hot, and Royal is off to one of the best starts of his career. However, the veteran is hardly the only receiver who has gotten off to a surprisingly fast start.

Here are a few of the receivers who fantasy owners should look at adding.

The Patriots have struggled on offense, but Julian Edelman is going to continue to put up big numbers for the foreseeable future.

Danny Amendola and Rob Gronkowski are both trying to work their way back from injuries, leaving Edelman as the only receiver who Tom Brady can trust. Last Thursday night against the Jets, Edelman caught 13 of Brady's 19 completions.

The 27-year-old has become a quality possession receiver in New England's offense. He has 157 receiving yards and two touchdowns on 20 receptions through two weeks.

Brady has to rely on Edelman and his rookie receivers until his squad gets healthy. Until then, Edelman is going to be the No. 1 target. Defenses will try to focus on him, but Brady has a way of getting his favorite receivers the ball.

Edelman's stock is rising quickly, so pick him up before it's too late.

Arizona has a strong quarterback in Carson Palmer and its receivers are already benefiting from the acquisition. Andre Roberts will be able to get open with Larry Fitzgerald drawing multiple defenders, so look to grab Roberts this week.

Palmer and Fitzgerald are going to put up big numbers this year, but the quarterback is looking for a second option. Michael Floyd has shown promise and Roberts has already put up quality numbers.

The 25-year-old Roberts has 11 receptions for 133 yards in two games. Once he and Palmer begin to establish a chemistry, his numbers should improve even more.

Roberts has good speed and good hands. He is a playmaker who will be productive with a strong-armed quarterback like Palmer.

Who has been the No. 1 fantasy receiver in the NFL this season? That would a guy who is owned in fewer than 20 percent of leagues—Eddie Royal.

Although he has only 114 receiving yards on 10 catches, Royal has put up 41 fantasy points. He has made his impact especially in the end zone, as he already has five touchdowns. By comparison, no other NFL receiver has three touchdowns this season.

Royal has benefited from Philip Rivers getting off to a strong start. The veteran quarterback has seven touchdowns with only one interception in leading the Chargers to a couple of high-scoring games.

Nobody knew who Rivers would be able to throw to after Danario Alexander was lost for the season, but Royal has stepped up. The 27-year-old has already tied his career-high in touchdowns and is on pace for his most yards since his rookie season.

Royal has been a big factor in San Diego's offense and he's available in most fantasy leagues. Get him while he's hot.
